Waste liquid treatment device for flow water extraction line

Abstract

The invention provides a waste liquid treatment device for a flow water extraction line. The device comprises a collecting barrel, a rectangular rod and a rectangular stop block, wherein an observingwindow is arranged in the upper position of the outer wall of the collecting barrel; the top end surface of a bottom cover is fixedly connected with a rectangular pillar; a U-shaped channel is formedin the rectangular pillar, and the rectangular rod is glidingly connected in a rectangular pipe. Through matched arrangement of the collecting barrel, the bottom cover and the rectangular pillar, theU-shaped channel is formed in the rectangular pillar, a rectangular hole is formed in the lower position of the left end surface of the rectangular pillar and communicated with the U-shaped channel, and at the moment, on one hand, when the liquid level reaches the top position of the U-shaped channel in the rectangular pillar, a liquid in the collecting barrel is drained out of the device throughthe U-shaped channel; on the other hand, the drainage speed is larger than the water inflow speed, so that after wastewater filtered in the collecting barrel is completely drained, a certain intervalexists to the next drainage, and a water receiving barrel can be replaced at this time.

Description

technical field [0001] The invention belongs to the technical field of bioengineering collection and filtration devices, and more specifically relates to a waste liquid treatment device for a water refining line. Background technique [0002] In many processes, liquid materials need to be filtered to remove impurities or other pollutants, such as: for bioengineering water extraction lines. Filtration is often accomplished by letting the liquid flow through the filter material; the usual method refers to a process in which the fluid is injected into the filter device and passed through a filter material such as a multi-layer filter for multiple filtration, and then discharged from the filter device after filtration. However, after filtering for a period of time, especially at the filter screen at the bottom, it is easy to cause the filter screen to be clogged due to the sedimentation and accumulation of debris, and the filtration efficiency is reduced. [0003] Based on the ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a waste liquid treatment device for water extraction line to solve the problem that the existing maintenance cycle is relatively short, and the existing waste liquid collection and filtration device for bioengineering water extraction line is When filtering, the waste liquid contains a lot of sundries. After a period of time, the filter screen at the bottom, especially due to the sedimentation and accumulation of sundries, will easily cause the filter screen to be blocked, resulting in slow drainage. At this time, it needs to be removed. Cleaning and maintenance will affect the filtration efficiency to a certain extent; automatic circulation is not convenient enough, and the collection and filtration devices used on the existing water extraction line often need to be manually closed and filtered when the water receiving bucket is full and the next water receiving bucket needs to be replaced Replace the water receiving bucket after the installation, and adjust the corresponding water receiving line to automatically receive water according to the time period of drainage, so as to improve the degree of automation; the filtering effect is poor, and the existing filtering devices often adopt the method of reducing the filter net in order to reduce the volume Quantity, the problem that multi-layer filtering cannot be realized in a smaller space by structural improvement
